dmesg output

In a newly installed debian wheezy (no non-free nvidia drivers around) nouveau
gives distorted graphics with a Geforce 4200Go (Dell inspiron 8500), see png
attached. The mouse pointer is distorted and the desktop difficultly usable.

This bug has been reported in debian
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=686611

The files I attach refer to

# cat /etc/X11/xorg.conf.d/98-me
Section "Device"
Identifier "Device0"
Driver "nouveau"
EndSection

and no other tricks, but I've also tried:

1) boot with nouveau.noaccel=1 in kernel line
   TTY and X badly screwed up

2) boot with nouveau.nofbaccel=1 in kernel line
   TTY badly screwed up, X distorted as in the plain case

3) boot with Option "NoAccel" "On"
X distorted

4) Booted with experimenta kernel
linux-image-3.5-trunk-686-pae   
Version: 3.5.2-1~experimental.1
black TTY and black X so I cannot document this.
